OIL-DISPENSING- DEVICE.

Application filed July 13, 1925. Serial No. 43,194.

' This invention relates to improvements in oil dispensing devices.

Since the number'of automobiles in this country became so numerous, the sale of oil and gasoline has become a large business and the method of dispensing thesame has been sy'stematized to a great extent. As greater quantities of gasoline are sold than oil, inventors have centered their efforts on the line with the result that only crude devices have been produced for use in dispensing oil. 'As the custom of buying oil in small quantities at the time that gasoline is bought insteadof, as was usually done some time ago, buying oil in five gallon lots and storing the same in the garage, it becomes necessary to provide means whereby oil may be dispensed asconveniently as gasoline. As there are a large number of different grades of oil and different cars require different grades it is necessary for filling stations to carry many different grades in stock which makes it more complicated than gasoline dispensing as only one or two grades of gasoline are handled by each station.

It is the. object of thisinvention to produce an oil dispensing device that shall be so constructed that a large number of differ- 39 ent grades of oil can be readily handled and in which the oil may be stored in conveniently placed tanks located underground or at some other'convenient place and connected to the dispensingdevice by means ofpipes. The oil in the storage-tanks may be subjected to air pressure of suficient value to cause it to flow to the dispensing device and out through'the molasses gates, with which the latter is equipped, whenever the gates are opened; As the purchaser'usually des res to see a sample of the oil before purchasing, a glass container is provided for each grade of 1 oil. 'A glass tube of somewhat smaller external diameter than the inside diameter and the 'oil poured into the space between the container and the tube so as toform a thin layer. 'An incandescent lamp is placed within the tube so as to'illuminate the mterior whereby the color characteristics of the oil become clearly visible.

In order to describe my invention with greater clearnes's and particularity so that the construction and mode of operation can be more readily understood, reference will be 1 production of devices for dispensing gaso of'the container is placed within the latterhad to the accompanying drawing in which the preferred construction and in which:

Fig. at is a section taken on line 4. ,4:,

Fig. 5 is a section taken on line 5.5, Fig 1 and 1 Fi .2.

The invention comprises a base member 1 and a drain table 2 that are connected together and held in assembled relation by means of bolts 3 and spacer pipes l. The

bolts and spacers extend from lugs 6 on the drain table to lugs 7 on the base. The drain table has a downwardly extending flange 8 and the base a similar upwardly extending flange 9 to which the sheet metal sides 10 are secured by means of screws 11. The

thereof is shown 6 is a section taken on line 6-6,

sides are formed from two sheets each of which extends one-half of the distance around and the joint between the abutting ends of the plate are covered by nickled strips 12. One side 10 has an opening that is closed by means of a door 18 which is secured in place by means of hinges 14 and which may be held in locked position by means of a lock 15. Secured in horizontal position to the inside of each side is an angle iron 16 that supports the end of a trans verse shelf member 17 which serves as a support for the measures which have been shown dotted. The shelf or support 17 is inclined towards the center and provided with a hole 18 through which oil may drain.

The drain table 1 has a central longitudinal opening 19 that is surrounded by an upwardly extending flange 20. At each end.

of the opening 19 I have provided lugs 21 that are perforated for the reception of bolts 22 whose upper ends 23 are threadedly connected to the bottom of the dispensing head or manifold 24. Pipes 25 surround the bolts 22 and serve as spacers. The manifold 24- has a downwardly extending flange 26. Sheet metal sides 27 whose outer surfaces are nickel plated extend between the flanges 20 and 26 so as to form an enclosed space or chamber that extends from the table to the manifold. The dispensing head or manifold Ql is a hollow casting whose interior is divided into eight chambers 28 by means of transverse walls 29. The central transverse wall has been designated by the numeral 30 as it differs from the others and has an opening through which the electrical conduit 31 passes. The two opposite sides of each chamber have threaded openings for the reception of the molasses gates 32 (see Fig. 3) and the bottom of each chamber has a threaded opening for the reception of a supply pipe 33 whose other end connected with the oil supply tank (not shown). In accordance with the usual practice followed in dispensing gasoline, the oil in the tanks is subjected to air pressure and when any one of the gates is open, oil will [low from the correspondingly supply tank through the connecting pipe 33 into the chamber 28 in a manner common and well understood. The upper surface of the drain table 1 is provided with a plurality of parallel grooves 3-l that connect with the central transverse grooves 35 whose inner ends terminate in holes 36. The grooves 3t slant towards the transverse groove so that any oil that may get onto the table will drain towards the transverse groove and down through the holes 36. I want to call particular attention to the fact that my device is so constructed that oil can be drawn from both sides of each compartment at once so that the capacity for service is doubled over what it would be if each compartment had only a single outlet. If the object were merely to dispense oil the apparatus so far described would be sulttcient, but as explained above, the purchaser always desires to see the oil before he buys. It is therefore desirable to have a sample of each grade of oil directly above the gates from which it is drawn. I have therefore provided the upper surface of the manifold with a circular depression 37 above each of the chambers 28. These depressions serve to receive the bottoms of the cylindrical glass containers 38 which are eparated from the bottom of the depres' n by some spacer 39. Within the containers 38 I place glass tubes a0 which have one end open and the other end closed. The bottom of the tube l0 rests upon the bottom of the container within which it is placed and is of such length that its upper end projects above the upper end of the container. The outer diameter of the tube +l0 is slightly less than the interior diameter of the container whereby an annular cylindrical space ll is formed for the reception of the oil. A top casting 4-2 is provided with recesses d3 of the proper SIZO to receive the upper ends of the containers 3S and concentric openings lt through which the upper ends to the tubes at) extend. The ends of the containers 3S and the sides of the tubes l0 are spaced from the adjacent metal surfaces by washers and rings of yielding material. The top member d2 has an outer flange 45. In order to display the oil samples to the best advantage, it is necessary to place an electric lamp inside of each of the tubes 10 and for this purpose I have provided a bar -lG to the underside of which I have secured electric sockets l7 each of which is located directly above one of the tubes l0. tiecured to each socket is an elongated lamp lb of the type which has one long lilament that extends the whole length of the lamp. The bar 46 is secured to the holding bolts l9 which also serve to hold the top member s2 and the cover member 50 which has a central opening and carries a shade holder 51 to which the globe 52 is secured. A lamp 53 is connected to the socket 5t and serves to illuminate the globe tings 55 surround the container 38 near their base and serve to prevent dust and dirt from accumulating in the sharp angles.

From the above it will be evident that I have produced an oil dispensing device that is so constructed that a large number of dilierent grades of oils or lubricants can be kept in stock and readily dispensed and which is provided with display devices which contain samples of the oil or lubricant and which are illuminated from the inside whereby the samples can be clearly seen at night and which produces and attractive appearance.

Having now described my invention what I claim as new is:
